Walk-AroundThe new PC80MR-3 compact midi-excavator is the result of the competence and technol-

ogy that Komatsu has acquired over the past 80 years. It was designed and developed with

constant attention to the needs of customers from all over the world. The end product is a

user-friendly machine with top-class performances. It has a tight tail swing that protrudes over

the tracks by just 145 mm. The operator can concentrate on his work, without having to worry

about rear-swing impacts.

First-Class Operator ComfortOperator’s environment

The PC80MR-3 is a compact ma-

chine, with a spacious and comfort-

able cab designed with care down

to the smallest detail. Particular

attention was given to the internal

layout, an adjustable seat, a large

digital panel in perfect view of the

operator, ergonomic and dedicated

PPC controls, and an effi cient

heating and ventilation system

with partial fresh air intake. A new

air-conditioning system, in option,

will maintain a perfect tempera-

ture inside the cab, no matter the

weather.

More comfort

Extensive proofi ng reduces noise

levels and creates a more pleasant

and comfortable work environment

inside the strong cab, designed to

guarantee maximum safety in case

of roll-over. Comfort - and safety -

is further enhanced by the 360º all-

round visibility, by an opening side

window and by an upper-rail sliding

door that can be opened even in

the tightest spaces.

5

Cutting-Edge Hydraulic Circuit

CLSS Hydraulic system

The PC80MR-3 is equipped with CLSS (Closed-centre Load

Sensing System). This exclusive system delivers hydraulic power

on demand, when and where the operator needs it. Combined

with a powerful engine, CLSS ensures high performances and

perfect control, independently from the load, in even the rough-

est working conditions.

6

Outstanding PerformancesAbsolute control

The PPC servo controls allow

extremely precise movements with

very little effort. To simplify and

speed up working cycles, all move-

ments can be done simultaneously,

and each has its own dedicated

control. Smooth manoeuvring

combined with a perfect view of the

working area, guarantees maximum

productivity for even the toughest

jobs.

A speed sensor - and two power modes

To optimize power usage, the

PC80MR-3 is fi tted with an engine

speed sensor .The main pump’s

power is automatically adjusted to

the engine speed and the compu-

terised system keeps this speed

constant during high load condi-

tions. Two distinct hydraulic power

modes - ‘Power’ or ‘Economy’ - let

the operator conveniently choose

between maximum power or mini-

mum fuel consumption.

7

Total Versatility

Versatility

The PC80MR-3 was specially de-

signed for applications that require

a high digging force and excellent

stability - and for work in confi ned

areas such as house building sites,

road works, and urban jobsites,

or for digging trenches near walls.

It offers all the features of a tradi-

tional excavator, but in an extremely

compact and easily transportable

machine. The many available op-

tions allow any operator to custom-

ize the machine to his needs: short

or long digging arm; 450 or 600 mm

steel tracks, 450 mm rubber tracks

or 450 mm roadliner. An additional

counterweight can be installed to

easily increase the lifting capacity.

Attachment lines

The 1 / 2 way auxiliary hydraulic cir-

cuit allows the use of a wide range

of working tools such as a hammer,

a clamshell bucket, an auger etc.

An optional auxiliary line is avail-

able for attachments that require

multiple hydraulic actuation. Upon

request, fi nal valves are available

for the equipment circuits.

8

Easy MaintenanceExcellent serviceability

With two big bonnets that

be easily opened even in t

spaces, the PC80MR-3 is

top level machine when it

maintenance. The main va

plastic fuel tank, and the o

are under the side bonnet

accessible from ground le

engine is under the rear co

all regular check points w

easy reach. The track fram

is sloped to prevent dirt fr

accumulating. ORFS hydr

face seal connectors and

electrical connectors enha

machine’s reliability and m

repairs faster and easier.

The battery main switch is standard Rear bonnet for quick engine check and

access to maintenance points from ground

level

Right bonnet for easy access to main control

valve, fuel tank, oil tank and tool box

When removing bucket, linkage or cylinder, lifting capacities can be increased by their respective weights.

– Reach from swing centre

– Bucket hook height

– Lifting capacities, including bucket (175 kg),

bucket linkage and bucket cylinder

– Rating over front

– Rating over side

– Rating at maximum reach

Ratings are based on ISO standard 10567. Rated loads do not exceed 87% of hydraulic lift capacity or 75% of tipping load. Excavators used in object handling

operations must comply with the related local regulations and must be equipped with hose burst valves (boom & arm) and an overload warning device in

compliance with EN474-5.

- The values marked with an asterisk (*) are limited by the hydraulic capacities

- Calculations are based on the machine resting on a uniform and fi rm surface

- The lifting point is a hypothetical hook placed behind the bucket.
